Application filed March 10, 1919. Serial No. 281,611.

To all to from it may concern Be it known that I, I-LENRY F. DAVIS, a citizen of the United States, residing at 1V alter, in the county of Comanche, State of Oklahoma, have invented certain new and useful Improvements in Flytraps for Screen Doors and li indows; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in fly traps'and particularly to fly traps which are incorporated in screen doors and windows.

One object of the present invention is to provide a novel and improved structure of this character which will effectively trap flies which crawl on the inner and outer faces of the door or window, thereby preventing their escape to the outer air or into the house.

Another object is to provide a novel. and eflicieut fly trap which is incorporated in the door or window construction and which will collect the trapped flies in such manner as to readily permit the removal and destruction thereof.

Other objects and advantages will be apparent from the following description when taken in connection with the accompanying drawings In the drawing.

Figure l is an elevation of a window screen incorporating my improved fly trap.

Fig. 2 is a horizontal sectional view taken on the line 22 of Fig. 1.

Fig. 3 is a vertical sectional view taken on the line 3-3 of Fig. 1.

Fig. 41 is a front elevation of a screen door having my trap incorporated therein.

Fig. 5 is a vertical longitudinal sectional view taken on the line 5-5 of Fig. 4:.

Fig. 6 is a vertical sectional view through one of the doors and strip to which it is hinged. taken on the line 66 of Fig. 1.

Referring to the accompanying drawings, and particularly to Figs. 1, 2, and 3, 10 represents the frame of the window screen. Secured to the outer face of the frame is a sheet of Wire screen 11 and similarly secured to the inner face thereof is a sheet of wirescreen 12. These two screens are thus spaced apart a distance equal to the thickness ofthe frame, as will readily be seen on the drawings. The lower central por tion of the inner screen 12 is formed with an opening 13 which extends a suitable distance upwardly, and at each side of this opening there are formed the receptacles 14 for the flies which have been trapped. Each of the receptacles has a door 15 which may be opened to remove the flies so caught. By reference to Fig. 6, it will be seen that the strips 10, on which the doors 15 are hinged, are of a thickness less than the distance between the screens 11 and 12, whereby a space is provided between the strips and the screen 12 for the flies to enter the receptrades. The screens 11 and 12 form the inner and outer wall is of the receptacles while vertical walls 16, which extend between said screens and are connected thereto, form the inner side walls thereof, and prevent escape of the flies from the receptacles, as well as to prevent direct entrance thereinto from the opening 13. These walls 16 extend up wardly between the screens 11 and 12' and converge, as at 17, at their upper ends to form the entrance opening for the flies to gain access to the space between the screens. ilnce having gotten between the screens the flies cannot escape, but will fall into the receptacles at the bottom. The natural tendcncy of flies is to crawl upwardly, and taking advantage of this tendency, provision is made, by means of the opening 13, whereby the flies will be permitted to crawl without obstruction, upwardly through the opening at 17, and into the space between the screens 11 and 12.

The same principle is applied to a screen door, as seen in Figs. 4 and 5, but in this application of the invention there is provided an opening 18, similar to the opening 13, on the outside of the door, below the mid-rail 19, and an opening on the inside of the door above the mid-rail. Thus flies on the inside of the house will be caught upon trying to escape to the outside. while those seeking to enter the house will be caught by entering through the opening 18.

There is thus provided a novel and eliicient device whereby flies will be caught, and subsequently destroyed, both when seeking to escape into or out of the house. Ordinarily traps incorporated in screen doors and windows simply provide for the escape ofthe flies from the inside to the outside, or vice versa.

' What is-claimed is:

A fiy trap comprising a frame, a screen covering one side of the frame, a second screen partially covering the other side of the frame and having its lower edge terminating above the lower end of the frame and formed with a central notch, transverse walls extending inwardly from the sides of a the frame and having those portions of the lower edgeof theseoond screen at opposite sides of the notch secured thereto, vertical parallel Walls extending from the bottom of the frame to the inner ends of the transverse wallsfand cooperatingwith the adjacent sides of the frame and the transverse walls to form fly receiving chambers, upwardly converging walls extendlng from the upper ends of the vertical walls and having HENRY DAVIS.
